[0002] Hydrogen electrolysis devices apply an external power source, causing cations and anions in an electrolyte solution (usually water) to move in a directional manner under the influence of an electric field.

[0060] A collecting plate 5 is fixed on the sliding seat 3 and has two outlets 11, which are an oxygen mixture outlet and a hydrogen mixture outlet respectively;

[0069] The bipolar plates 61 are configured in two pieces and are both mounted on the expansion column 7 and the adjustment assembly 8;

[0070] There are two backing plates 62 , each fixed on one side of the two bipolar plates 61 close to each other;

[0071] There are two clamping plates 63, each fixed on one side of the two pads 62 close to each other;

[0072] The anode electrode 64 and the cathode electrode 65 are respectively slidably disposed in the two pads 62, and a connecting plate 66 is slidably disposed on each of the anode electrode 64 and the cathode electrode 65, and the connecting plate 66 is fixed between the pad 62 and the clamping plate 63;

[0073] The diaphragm 67 is clamped and fixed by the two clamping plates 63 and is located between the anode electrode 64 and the cathode electrode 65 .

[0074] It should be noted that the connection plates 66 on the anode electrodes 64 and cathode electrodes 65 in the multiple electrolysis components 6 are connected respectively through conductive columns, thereby forming the anode and cathode during electrolysis.

[0075] As a preferred embodiment, the bipolar plates 61 close to the fixed plate 2 , the sliding plate 4 and the collecting plate 5 are fixedly connected thereto, and the remaining bipolar plates 61 are slidably arranged on the expansion column 7 and the adjustment assembly 8 .

[0078] That is, when the deployment column 7 rotates, the bipolar plate 61 that is farther away from the fixed plate 2 has a longer sliding distance, thereby facilitating the synchronous deployment of multiple electrolytic assemblies 6 .

[0079] As a preferred embodiment, the conversion component 23 includes:

[0080] The fixing seat 235 is fixed in the fixing plate 2 and a connecting rod 236 is rotatably provided on the fixing seat 235. The connecting rod 236 is a telescopic rod.

[0081] A first sliding post 231 is slidably disposed in the deployment post 7 , with one end of the first sliding post being fixedly connected to the limiting post 72 and the other end of the first sliding post being slidably connected to the driven gear 22 ;

At this time, the connecting rod 236 drives the second adjustment ring 234 away from the drive gear 21, so that the second sliding column 233 is disengaged from the drive gear 21. Then the adjustment motor 9 is driven to rotate the expansion column 7 to expand the electrolytic component 6. At this time, the anode electrode 64 moves synchronously with the bipolar plate 61 and drives the adjustment component 8 to slide, so that the adjustment component 8 is expanded, which facilitates the removal of the diaphragm 67.

[0086] As a preferred embodiment, the adjustment component 8 includes:

[0087] A rotating column 81 is rotatably disposed in the fixed plate 2 and is slidably connected to the second sliding column 233;

[0091] That is, when the anode electrode 64 moves synchronously with the bipolar plate 61 , the adjusting thread 83 causes the anode electrode 64 to drive the receiving column 84 to slide synchronously, thereby facilitating the disengagement of the connecting column 85 from the sliding groove 82 .

[0092] Specifically, the electrolyte is first injected through the electrolyte inlet 10 to enter the electrolysis component 6, and then electrolysis is carried out to produce hydrogen. The electrolyte after electrolysis is discharged through the outlet 11 to obtain an oxygen mixture and a hydrogen mixture. Then the oxygen mixture and the hydrogen mixture are separated into gas and liquid by separation equipment, thereby completing the hydrogen production operation. When the diaphragm 67 is replaced, the first sliding column 231 is first pressed into the driven gear 22 by pressing the limit column 72. At this time, the connecting rod 236 drives the second adjustment ring 234 away from the drive gear 21, so that the second sliding column 233 is disengaged from the drive gear 21. Then the adjustment motor 9 is driven to rotate the expansion column 7 to expand the electrolysis component 6. At this time, the anode electrode 64 moves synchronously with the bipolar plate 61 and drives the adjustment component 8 to slide, so that the adjustment component 8 is expanded, which is convenient for removing the diaphragm 67.

[0093] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
